The babies I know yet don't sleep like adults which means that you will be up at night at random hours that you are not used to and I think this has nothing to do with industrial work culture. That 6-8 hours of uninterrupted sleep is just a "dream" :).

I recall, as a twins dad, I did not have 2+ hours of uninterrupted sleep till they are 2 years old. (This depends on the kid though).

Prior to the industrial revolution polyphasic sleep was pretty standard:

		That article does not say whether polyphasic sleep was standard because parents were synchronizing with their babies.
